I've never seen the drawing-style before, but there are so many manga's out there... The story is follows the basic old plot of mother becoming slave to the son. The mother looks pretty nice. Nothing too big but still attractive.
The son looks like a psychopath, always with half a smirk on his face when he's doing his mom. "Yeah, I'm doing my mom, I'm making her suffer, hur hur hur"
I don't like the kid... he seems clichéd and completely limited to his desire to be some kind of self-declared badass.
The beginning of this Comic was pretty good, where it introduced the characters and the son started raping his mother.
Which brings me to my second point: That during image 12, the comic officially became (softcore?) guro. It wasn't as bad as The REALLY BAD SHIT out there, but it was still enough to turn my stomach a little. While I wouldn't say that that ruined the comic for me, it definitely hurt it in my eyes.
